Answer:
x = 18
Step-by-step explanation:
This problem can be solved using concept of Pythagoras theorem.
Pythagoras theorem states that in a right angled triangle, if "a" and "b" are sides containing the right angle and h is hypotenuse then the relation between them is 
_________________________________________
Given in the problem
a = 24
b = x
h = x+12
applying Pythagoras theorem

for (x+12)^2 we have used formula 
Thus, value of x is 18.
Answer:
3x + 7 + 2x -1
Step-by-step explanation:

Answer:
8 nickels
Step-by-step explanation:
Let n be the number of nickels.
4: (2+ 6 + 4 + n) = 1:5
4÷(12 + n) = 1÷5
4 x 5 = 1 x (12 + n)
20 = 12 + n
n = 8
